To all whom it may concern:

Be it known that I, JOSEPH C. HARVEY, a

' citizen of the United States, residing in Chithe; individual ledger orother record sheet 1s nois, have invented certain new and usefulImprovements in Type-Writing .Machines, of which the following isaspecification."

This invention relates to means for. 10- cating two or more sheets in atypewriting machine, and making duplicate typewritten impressionsthereon, and is particularly use- .ful in bookkeeping operations, where'an entry is made simultaneously on a ledger sheet and a statement; andit is also useful in billing operations and the like, as for instancewhere it is. desired to make upon a journal or other record sheetduplicates of the individual' entries madeupon a number of bills,statements or other individual sheets.

According to one feature of my'inventicn',

assembled in the'machine with an interleaving ink strip, which may be ofthe same material as an ordinary inking ribbon, but which-is retainedmechanically in the machine for repeated use, thus avoiding thenecessityof using carbon sheets and also gaming the advantage of making apermanent or record copy. A further advantage 1s gained in connectionwith this inkin, strip,

inasmuch as it is madeto disappear a ter the entries are typewritten, s0that when the .statementis withdrawn, theoperator caninspect the entrymade. on the record sheet which is retained in the machine, and maycorrect the same or ire-adjust the sheet, or, in

the, case of condensed billing, may advance .the sheet to give. therequired space between successive entries on the record'sheet. :This inkstrip is preferably formed upon the forwardborder bf a web, which at tsrear end is'connectedby a spring device to the typewriter, for thepurpose'ofretnrnlng the ink strip to normal position, or causing it todisappear. The sheets-and strip are all fed forwardly bythe usual feedroll runn1n,g; upon the platen, and when said 'feed roll is re? leasedand the statement is withdrawn, the

strip is automatically returned by means of said spring. 7

According to'another feature of the mvention, one of the work sheets,usually the ledger sheet, is laid upon a special work table which -is.arranged behind the platen in front of the usual paper shelf, and apres- Specification of Letters Patent.

.of contact with the platen. Fig. 71is a diagram to illustrate themethod of introducing the-ledger or other record sheetinto' the machine;the leading edge of the sheet being shown as resting upon the crownofthe special feed roll. Fig. 8 is a diagram to illus trate the manner inwhich the record sheet is'fed around by revolving the platen until itsfrontedge emerges above the front scale. Fig. 9;is a view like Fig. 3,but showing the writtenstatement as being partly inthe machine. Fig. 10is a diagram to show the sheets with the intervening ink strip as havingbeen advanoed by rotating the platen, to bring them topo'sition to beginthefirstline of writing. Fig-11 is a diagram to showthe introduction ofthe individual sheet after the record sheet has been introduced.

The cylindrical platen 1 is mounted by I itsaxle 2 in the ends'3, 4: ofa .platen frame, which are connected by a paper shelf5, ex-

tendingdownwardly and forwardly to the" platen upon the introductoryside thereof.

Rods 6 and 7 also rigidly connect the platen frame ends. A guiding apron8 usually curves forwardly from the lower end of the ing operations, isto remain in the machine and receive all the typewritten items whichappear uponthe bills, statements or individual work-sheets, is laiduponja supplemental work table or shelf 12, which may incline downwardlyand forwardly with its lower end near the platen 1. This sheetis carriedaround under the platen and up in front thereof, and adjusted in respectto the printing line by means of the usual scales 13.

The "bill, statement or other individual work-sheet 14: is laid upon thepaper shelf 5, and guided around the platen and ad justed to the scales13. The usual roll 15 on the underside of the platen is used to feedthe. sheets forwardly after they are inserted; but is cast off whilethey are being introduced.

. Between therecord or-general work-sheet 11 and the individualsheet14., lies an inking strip 16, which enables the type to make impressionson the under sheet 11 corresponding to the typed impressions 'on theouter sheet 14. This inking strip normally occupies the position seen atFig. 2, with its advance edge flush with or below the edges of thescales '13, so as not to interfere with the adjustment of thework-sheets 11 and 14'to said scales.

Thelength of the inking strip is equal to or greater than the length ofthe line of: writing upon the work-sheets. This inking 'strip remains inthe'machine', being adapted to feed up with the work-sheets as thelatter are'written lineby line, [and then returning to the normal Fig. 2position, thus disclosing the writing on the record sheet 11, and alsopermitting the latter to be readjusted if required.

The inking strip 16' is flexible, and is connected by a flexible web 17to a returning device, which may be in the form of a lever 18, pivotedat 19 upon the rear side of table 12, and having a spring'20 which tendsconstantly to return the flexible web 17 and its'ink strip 16 to normalposition. The

;lever 18 is connected by a link 21 to a metal- --lic binding strip 22provided upon the flexible web 17, and preferably extending for somedistance along the opposite edges thereof, as at 23. The normal positionof the ink strip is determined by stops 24,

against which the binding strip 22 is held by means of the spring 20,Fig. 2.

The record sheet 11 is first inserted in the machine, Fig. 7, with itsbottom edge resting uponthe auxiliary roll or rolls 25, which aremounted by Ineans of an axle 26 in ears 27 pendent from the sides ofauxil iary work table 12. The sides of said table are bent up to formopposite gages 28, and

these are preferably spaced so that the work sheet 11 fits looselybetween them, so as to be gaged by one or both thereof. The leading edgeof a sheet catches momentarily upon the crown of roll 25, but the loweredge of the auxiliary table 12 is bent forwardly at29, Fig. 4, toprevent the sheet catching too far back on roll 25 to form a deflector.By rotating the platen by means of the usual knob 30, the sheet-11 isled or dropped between the roll 25 and-the platen.

It will be understood that the advance edge of 'the'work sheet 11 maybegaged or straightened by resting upon roll 25, but if said sheet shouldbe. a little askeW' at that time, it will be found to right itself whileit is dropping off the roll and into the bight of the roll 15 and theplaten 1; so that the side edges of the sheet will be parallel with theside gages 28. The sheet is pressed by said roll against the platen andfed forwardly down around and up in front of the platen, 8, between thelatter and the lllklllg strip 16. During this operation, roll 15 runningupon the under side of the platen, is cast off.

Preferably the necessary pressure of the feed roll 25 against the platenis effected by the weight of the auxiliary table 12, which may'have atits sides hooks 31 to pivot upon the rods 6; the weight of the shelfwith its" appurtenances being back of the pivot rod 6, thus causing theroll 25 (which @is beneath 'said rod) to swing forwardly against theplaten. To release roll 25, it 1s onlytnecessary to swing shelf 12forwardly. It is noted that the hooks 31 per mit the shelf 12 to bereadily detached from the machine-when it is desired to use the .samefor other work.

-When the operator has advanced the sheet 11 far enough, he may adjustit to the print ing line by means of scales 13; the inking strip 16 nothindering this operation, as it does. not at this time project abovesaid scales 13, Fig. 8. The operator then inserts the individualwork-sheet 14, Fig. 11, the same passing freely down around under theplaten and up in front thereof (the roll 15 being still cast off), andadjusts the sheet to the scales 13. The operatorthen lifts the key 31,and restores the roll 15. He then advances the platen the distance ofone or more line-spaces, either by means of the strip 16, so that theywillall project above the scales 13, Fig. 10. The record sheet 11-- mayproject farther than the other two.

- The operator then writes the line by means this manner.

'of the usual types 10, Fig. 3, and in some cases, he may write severallines, advancing the platen by means of said line-space mech anism,together-with said work-sheets 11 and 14, and ink strip 16;'the spring20 yielding to permit the ink strip 16 to be advanced in It will beunderstood that the roll 15'is effective to feed the strip 16 as well asthe sheets. Having completed the entry upon the statement, the operatordepresses the key 31 to cast off the roll 15, and then draws theindividual sheet 14 forwardly to remove it from the machine. The.

tensionof spring 20 is very light, so that the upward pressure of theusual yielding apron 8, under the platen, is suflicient to detain theflexible web 17 while said sheet 14 is being drawn out, ('Fig. 9,) untilthe latter is nearly or quite withdrawn from the platen. This releasesweb 17, and the spring 20 returns the-latter and strip 16 to normal Fig.2 position. The record sheet 11, of course, is not disturbed'while theindividual sheet 14 is being withdrawn, nor while the ink strip .16 isretracted; The operator now inserts a fresh sheet 14 and adjusts it tothe printing line as befdre.

the forward portion ofthe flexible-web 17,

which may consist of cloth similar to that of which typewriter inkribbons are made. The cloth needs to be inked only on one side; andtheother side thereof may have jan' impermeable coating 33, as indicated atFig.- 1 so as n t to offset on the rear face of the front work-sheet14.

It will be understood that the retraction or disappearance of the 'inkstrip l6 exposes the type impressions on the sheet 11,

so that the operator can examine the same and correct them ifnecessary,-and may also advance the sheet by turning the-knob 30 so asto leave any required amount of space between successive entries on therecord sheet 11; or he may further adjust said sheet to bring anydesired ruled line thereon to register with the scales 13.

Having adjusted the fresh sheet 14, the operator restores the feed roll15, and proceeds to typewrite the new entry, which is and leaves areproperly filed, and when the of course written in the desired ,placeupon the new sheet, and also appears in proper location beneath theprevious entry on the record sheet 11. Thus the insertion and withdrawalof the sheets 14 proceeds untilthe sheet 11 is filled; whereupon'a,fresh record sheet 11 is inserted, and the operation contlnues-Instead'of having the rol l -25- run upon the platen; it' may cooperatewith another roll 34, Fig. 6, to feed thefsheets' 11 to .the platen andforwardly around the same while the latter remains stationary, the roll25 being provided for this purpose with a fingerwheel 35. These rolls 25and 34-may rotate 8 idly when sheet l1 is being drawn forward by thecotipera-tionof the platen 1 with the bottom roll 15. j I

While the improvements have been de-. scribed in connection with theoperation of condensed billing, it will be understood that, a use of.the machine which is of equal or greater value, is its use forbookkeeping purposes. In this connection the record sheet is usually aloose leaf of a ledger; and the individual sheet is. a statement of'account, In using the invention for this purpose, the operator, afterwithdrawing the. individual sheet, also withdraws the-recordsheet 11,since the latter bears at its top the name of a single customer, andonly that customers items are entered thereon. After the various itemsareentered on the several statements and ledger leaves, both statementsnext transaction occurs with any customer, his statement and ledger leafare selected and the item entered thereon, where ponf they are re-filedin their original places; Thus the ledger sheet constantly shows thecondition'of the customers account, while the statement is added to dayby day, so that at the end of the month it is all. ready formailing'without further labor.

One of the great advantages-of the 'pres-- n ent invention is that itfacilitates'the intro duction of the ledger sheet and the adjustmentthereof to the printing line without] being obscured by a carbon orother inking device, such as usually covers the face of the record sheetin condensed billing and other operations. The operator may not only,easily see the last line of writing on the ledger sheet, but may quicklyadjust the same to the printing line by means of the usual frontscales13. Thus it will be seen that the sheets may be easily insertedindependently of each other and each properly adjusted to the printingline independently of the position occupied by the other, while each maybe quickly-withdrawn when the roll 15 is cast off and thus the operationof bookkeeping is greatly simplified and facilitated, particularly wherethe -amounts are added by means of a computing attachment are not quiteso clearas those on the outer sheet; and it is therefore optionalwhether the statement or the ledger sheet shall receive the clearerimpressions- I Variations may be resortedto within the scope of theinvention, and portions of the improvements may be used without others.Having thusdescribed my invention, I
